The Amazon river runs 4,000 miles from the
Andes to the sea, and is longer than any river but the Nile. The Amazon River is therefore the second longest river in the world. It is also the largest in terms of the size of its watershed, the number of tributaries, and the volume of water discharged into the sea. The vast
Amazon basin covers
more than two and a half million square miles, more than any other rainforests. No bridge crosses the river along its entire length.
